Excessive heat exposure during curing can leave some rubber compounds unable to meet their required properties. The extent of damage must be assessed from the process history and tests, not assumed to be minor because a fault was noticed quickly.
Verify temperature measurement, cure timing and equipment operation. If a batch experienced an uncontrolled process, identify the affected parts and evaluate them against the agreed acceptance criteria before release.
Storage and service degradation require a separate review of exposure conditions. Avoiding unnecessary heat and sunlight can help, but it does not eliminate every aging mechanism. Corrective action should address the confirmed cause and include verification of the replacement process or material.
